Crude oil in Fularchi heavy oilfield has high viscosity and low mobility. Conventional development is difficult and the effect of cyclic steam stimulation is also not ideal.

富拉尔基稠油油田原油粘度高，地下流动能力较低，常规开采较为困难，而蒸汽吞吐开采效果也不理想。

At normal temperatures, the oil driving efficiency and the sweep efficiency of water driving are low, and the crude viscosity increases after water drive.

常温驱油效率低，水驱波及系数小，且水驱后原油黏度增加。

Sweet light crude oil yields the most gallons of gasoline per barrel of oil and since it has low viscosity and low density, it is comparatively inexpensive to pump, transport, and refine.
